PAPER-STOCK-REFINIITG APPARATUS.

Specification of Letters Patent.

Patented Aug. 15, 1911.

Application filed May 20, 1911. Serial No. 628,453.

To all whom it may concern:

Be it known that I, GEORGE D. RYTHER, a citizen of the United States,residing at Carthage, in the county of Jelferson and State of New York,have invented certain new and useful Improvements in Paper-Stock-Refining Apparatus; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked'thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in apparatus fordisintegrating and refining paper stock and comprises essentially diskshaving concentrlc series of serrated flanges, the two series alternatelyarranged and designed to rotate in opposite directions.

The invention comprises various other details of construction andcombinations and arrangements of parts which will be hereinafter fullydescribed and then specifically defined in the appended claims,

I illustrate my invention in the accom panying drawings, in which Figure1 is an elevation of my apparatus for disintegrating and refining paperstocks, port-ions being cut away to better illustrate featuresof theinvention. .Fig. 2 is atop plan view. Fig. 3 is a cross sectional viewon line 33 of Fig. 1, and Fig. 4 is a sectional View on line 4-4;of-Fig. 2.

Reference now being had to the details of the drawings by letter, A, Adesignate standards supported by the bars B, one of which standardssupports the journal bear ings C and the other the bearings D. A hollowshaft E is mounted in the bearings D and the supplemental bearings D,which latter are provided with a suit-ably packed gland D Adjacent tothe bearing D is a chamber F with a threaded opening F leading theretoand to which latter a pipe, not shown, is adapted to be connected andaffording means whereby the stock may be fed from any suitablecsource ofsupply to the hollow shaft.

Upon reference to Fig, 4 of the drawings, it will be noted that thehollow shaft E has fixed thereto a disk H, the upper port-ion H r ofwhich is secured fast to the shaft and said disk is provided with acircumferential flange I and also a series of concentrically "arrangedflanges K, each of. which is provided with oppositely disposed wings Kwith inclined edges, said wings arranged in pairs and spaced apart, asshown clearly in Fig. 3 of the drawings.

A second shaft, designated by letter L, which is journaled in thebearings C, has a disk Nwith ahub portion N which is fixed thereto, saiddisk N being substantially similar to the disk H before described andprovided with concentric flanges O with wings 0 arranged opposite eachother and in pairs with their inclined edges parallel with thecorresponding inclined edges upon the flanges K. The inner edge of theflange I, it will be noted upon reference to Fig. 3 of the drawings, isprovided with a series of serrations I which cooperate with the outerwings upon the outermost of the flanges 0, Upon reference to Fig. 3, itwill be noted that the outer pointed edges of the wings upon the twoseries of alternately rotating flanges have slight clearances,sutficient only out interference.

In order to allow a longitudinal adjustment to the shaft L, a-thrustbearing Q, is provided and a set screw R mounted in suitable threadedbearings is provided to a pulley M thereon, forming means whereby powermay be applied to rotate' the shaft L, the two shafts being adapted tobe rotated in, opposite directions. A suitable casing T is provided as ahousing about the two disks and contains the stock as it upon the diskrotating in opposite direction. The casing T has an exit opening Tthrough which the refined stock may be passed to any suitable location;Projecting from each opposite face of the casing is a hollow hub portionS, having suitable bearturn.

In operation, the paper stock in liquid form is'fed to thehollow pipe Eand passes to and through the opening at the center of the disk H and isfed between. the two concentric series of rapidly rotating flanges and,owing to the peculiar shape of the wings stock will be thrown by theinclined edges of the wings toward the inclined edges of shaft and asimilar pulley M is fixed to the is refined by the action of theserrations upon the flanges, it will be noted that the" to allow thewings to pass one another withactuate the thrust bearing. The shaft Ehasings S therein through which the. shafts Y the wings upon the flangeswhich rotate in the opposite direction and, by the time the stockreaches the outermost of the flanges,

An apparatus for disintegrating .and refining paper stockcomprising two shafts adapted to rotate in opposite directions, one ofsaid shafts being hollow, disks, one fastened to each shaft, each diskhaving a series of concentric flanges interlocking with one another, theopposite faces of said flanges having wings, and a casing about thedisks.

2. An apparatus for disintegrating and refining paper stock comprisingtwo shafts adapted to rotate in opposite directions, one of said shaftsbeing hollow, disks, one fastened to each shaft, each disk having aseries of concentric flanges interlocking with one another, the oppositefaces of said flanges having wings, a casing about the disks, and

means for adjusting one of said she fts longitudinally.

3. An apparatus for disintegrating and refining paper stock comprisingtwo shafts adapted to rotate in opposite direct-ions, one of said shaftsbeing hollow, tened to each shaft, each disk having a series ofconcentric flanges interlocking with one another, the opposite faces ofsaidflanges having wings, a casing about the disks, an.

disks, one fasadjusting screw, and thrust bearings actu- I and a casing.about said disks.

5. An apparatus for disintegrating and refining paper stock comprisingtwo shafts adapted to rotate in opposite directions, one of said shaftsbeing hollow, disks, one fastened to each shaft, each disk having aseries of concentric flanges interlocking with one another, the oppositefaces oflsaid flanges having oppositely disposed wings, the'edges of thewings upon one series of flanges being inclined and parallel with theinclined edges upon the other series of flanges, and a casing aboutsaiddisks.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
